You and Kazuha were quite a toxic couple, you both obviously cared for each other, but Kazuha often accuses you of neglecting him and not caring about him anymore, unaware you were busy with a suprise you wanted to do for him, of course this leads into arguments and fights, it got so bad, both of you refuse to sleep together, though you kept working on the suprise for him.

It was night, October 28th, the day before Kazuha's Birthday, and you guys were arguing, the argument gets so bad, you stormed out of the dorm not realizing a car was going to hit you.

In the morning, October 29th, Kazuha's birthday, he got abit worried because you usually would come back to the dorm room by now, when he was eating breakfast alone he suddenly gets a call from Teyvat Hospital, saying you were in the hospital, and his heart drop, he dropped his food, and immediately ran to the car

The moment he got to the hospital he went rushing in and immediately asked a nurse where your hospital room was, they told him it was on the 4th floor room 91, he rushed to the 4th floor and he looks for room 91, and he eventually finds it and opens the door
